it would be a dead planet.
Photo synthetic organisms convert the energy of the sun to sugars etc. Part of this process release oxygen from the compound carbon dioxide. If the organisms that do this cease to exist then there would be no more food produced for animals to eat and the oxygen that we need to breath would eventually disappear into compounds of gasses that are of no use to animal life. In effect life on earth as we now know it would disappear

Where is the first living organism on earth in air or land water atmosphere?
The first living organisms on earth were a type of aquatic photosynthetic bacteria called cyanobacteria (blue-green algae). These organisms formed structures called stromatolites. These organisms did not become extinct and still exist in both salt and fresh water environments.
Which is the correct order of organisms in terms of their appearance on Earth?
bacteria, trilobites, lizards, rhinoceros
How would the increasing number of photosynthesizing organisms on earth have affected both earth and its other organisms?
As the first photosynthetic organisms increased in number, the concentration of oxygen in Earth's atmosphere began to increase. Organisms that could respire aerobically would have evolved and thrived. The sun's rays would have converted much of the oxygen into ozone molecules that would then have formed a layer that contained more ozone than the rest of the atmosphere.
What is a place where organisms live?
A community is place where organisms live.
What is the function of organic molecules in unicellular organisms?
Organic molecules are the part of life we are living in earth... it is common for all level of organisms on earth.
What effect did photosynthetic cyanobacteria have on earth's environment?
Photosynthetic cyanobacteria were the first organisms to produce oxygen. The effect of their oxygen production was that the earth became an environment which was suitable for life.
Do humans have a effect on the evolution of the organisms on earth?
no
Why would all animals die if there were no more photosynthetic organisms on earth?
Yes, because all plants are photosynthetic, and the food chain starts with plants, so everything would die without plants.
How do we separate the geologic time scale into eras?
The main periods of geologic time are eons. Then eons are divided into eras. All these divisions are done using geological strata. That is, layers of earth or stone, etc. that represent periods of some kind of similar behavior on the earth.
What does earth do with sunlight from the sun?
Sunlight warms the earth, provides light for us to see, and light so that plants and other photosynthetic organisms can use the energy to make food.
Why is the greenhouse essential for life on earth?
The greenhouse effect is essential for life on earth because organisms must be kept at a warm enough temperature to grow. Without the greenhouse effect organisms wouldn't be warm enough.
What will be the effect on the living organisms if the earth becomes warmer?
we cant get enough water

Why is ozone disappearance a problem?
Ozone disappearing is a problem as it allows UV rays to allow enter the earth. They are fatal for life on earth.
What Were the first living things on earth photosynthetic?
Bacteria
